OPTICAL FIBER

Structure of optical fiber

Total internal reflection of optical fiber

Classification of optical fiberOptical fiber is classified into two

types . They are:-1.Number of modes2.Refractive indexBased on number of modes it is

classified into two types . They are:-1.Single Mode Fiber(SMF)2.Multi Mode Fiber(MMF)

Information source-It provides an electrical signal to transmitter comprising an electrical stage.

Electrical transmitter-It drives an optical source to give an modulation of light wave carrier.

Optical source-It provides the electrical-optical.

Conversion-It may be a semiconductor- laser or an LED.

APPLICATIONS:-• Optical fiber has wider range of

applications in almost all fields , some are specified below:

In telecommunication fieldIn space applicationsIn broadband applicationsIn computer industrial

applicationsIn mining applicationsIn medical applicationsIn military applications
